Description

Phototherapy device and electrodes

The present invention relates to a phototherapy device and an electrode rod used in the phototherapy device, which generates an arc discharge between a pair of electrodes, and uses the light generated by the arc discharge to prevent or treat diseases such as viral infections.

In the past, in the electrode rods used in phototherapy devices that generate arc discharges, the luminous intensity was extremely weak when using only carbon-containing electrodes, so in order to enhance the luminous intensity, some metals were also mixed in the electrode rods. Accustomed to know. Patent Document 1 discloses the technical content of "in order to enhance the luminous intensity, in addition to carbon, lanthanide elements such as cerium and lanthanum, rare earths, alkali metals, etc. are mixed."

By mixing metal into the electrode rods, the emission spectrum of the light generated by the arc discharge is changed. This is because the metal has an emission spectrum corresponding to the intrinsic wavelength band of the element. The width of the spectrum, within a single element, is almost as narrow regardless of the species. In addition, if one metal element is added, the number of emission peaks is basically one. In conventional electrode rods, the types of metals added are limited, and the number of luminescence peaks or the width of the wavelength band with peaks cannot be increased beyond the type of metal elements added or further expanded. However, the use of conventional phototherapy devices is limited to reducing body pain, improving circulation, and adjusting circadian rhythms through thermotherapy.

[Problem to be solved by the invention]

In conventional phototherapy devices, there is no idea of "adjusting the emission spectrum of light generated by arc discharge", and phototherapy devices using arc discharge have not been effectively used for purposes other than specific applications. The purpose of the present invention is to enhance and adjust the wavelength band of the light in an optimal manner, and at the same time improve the convenience of the phototherapy device, so that the light generated by the arc discharge can be effectively and widely used in the treatment of diseases such as viral infections. prevention or treatment.

Considering the safety or harmful effects on the human body at high temperatures caused by arc discharge, the types of metal elements that can be actually used in electrode rods are quite limited. For example, as far as non-metallic carbon is concerned, if inhalation of particulate pollutants from further high-temperature processed carbon nanotubes may cause lung fibrosis, pure carbon or graphite is preferred. Silicon compounds that emit infrared rays are also suspected of pneumoconiosis and carcinogenicity, and are not elements that can be used in arc discharge. Fluorescent lamps used in a glass-enclosed environment use calcium halophosphate compounds compounded with many harmful elements, which cannot be used in phototherapy devices. As mentioned above, we still have to take into account the adverse effects of the metal added to the electrode rod on the human body. [means to solve the problem]

The phototherapy device of the present invention includes: a pair of electrodes including carbon, titanium nitride, and potassium or a potassium compound; a supporting part that supports the pair of electrodes with a predetermined distance between the pair of electrodes; and an electronic circuit that applies a voltage to the pair of electrodes that causes an arc discharge to be generated between the pair of electrodes. In the phototherapy device constructed in the above manner, by adding titanium nitride to the electrode, the light absorption and scattering effect or the plasmon effect can be used to realize the luminescence with several luminous peaks increased. By irradiating light with a pattern that blocks the ultraviolet range but expands the wavelength band width, it can exhibit efficacy against viral and bacterial infections. In addition, we believe that titanium nitride is used in artificial joints, etc., has high biocompatibility, and has little adverse effects on the human body.

In this configuration, the pair of electrodes may further include silver or calcium. In the phototherapy device constructed in the above manner, by adding silver or calcium to the electrode, the luminous intensity in the near-infrared range can be enhanced, thereby enhancing the therapeutic effect on the living body. In addition, it can reduce harmful ultraviolet wavelengths such as UVB (ultraviolet B, ultraviolet B) and UVC (ultraviolet C, ultraviolet C).

In this configuration, an adsorbent for absorbing carbon dioxide generated by arc discharge may be further provided, and the adsorbent is configured to include clay powder, wood ash, charcoal, and zeolite. In the phototherapy device constructed in the above manner, carbon dioxide or metal oxides generated by combustion are absorbed by the absorbing material, whereby the user is prevented from inhaling the generated substances directly, or from discharging them into the outside atmosphere as they are .

In this configuration, it is also possible to constitute a structure "further including a fan provided in the vicinity of the pair of electrodes to guide the carbon dioxide to the adsorbent". In the phototherapy device constructed in the above manner, adsorption of carbon dioxide or metal oxides by the absorbing material can be promoted.

In this configuration, the electronic circuit can also be composed of MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor, Metal-Oxide-Semiconductor Field-Effect Transistor) or IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor) in internal structure. In the phototherapy device configured as described above, it is possible to reduce the size and weight of the phototherapy device compared with the conventional method using a large transformer. In this way, the phototherapy device can be easily held and carried.

In this configuration, it is also possible to configure a structure that "further includes a metal reflection plate that reflects light generated by arc discharge, and a groove is formed in the reflection plate". In the phototherapy device constructed in the above manner, the intensity of the light can be enhanced and the light can be generated with the minimum electric power. [Efficacy of the invention]

According to the present invention, the light generated by arc discharge can be effectively and widely used in the prevention or treatment of diseases such as viral infections.

By applying a voltage to the pair of electrode rods 10 by an electronic circuit built in the main body 30 , an arc discharge is generated between the pair of electrode rods 10 , and light is generated by the arc discharge. By irradiating the generated light onto the user's body or the like through the opening of the cover portion 21, the luminescent energy of the light is used for the prevention or treatment of diseases such as viral infections.

FIG. 2 is a perspective view of the electrode rod 10 used in the phototherapy device 1 . As shown in FIG. 2 , the electrode rod 10 is composed of a cylindrical core part 11 for generating arc discharge, and an aggregate part 12 covering and protecting the periphery of the core part 11 . The aggregate part 12 is obtained by mixing carbon bone materials such as petroleum coke and graphite powder, and binding materials such as tar or thermosetting resin, and firing and curing at 1000°C. In order to improve combustion efficiency, 20-30% sulfur can also be mixed. The aggregate part 12 is designed in the shape of a cylindrical rod with a diameter of about 5-10 mm. The central part of the aggregate part 12 is cut out by about 2mm, and the material mixed with the core part 11 is injected into the hollow part, and then fired and solidified again.

FIG. 3 is a diagram showing the internal structure of the irradiation unit 20 in which the pair of electrode rods 10 are arranged. The outside of the irradiation unit 20 is shown by a dotted line, and the structure arranged inside is shown by a solid line. The irradiation unit 20 has a cover unit 21 , a support unit 22 , a fan 23 , a thermoelectric cooler (Thermo Electric Cooler) 24 , and an adsorption unit 25 . The support portion 22 has a shape in which an inclined surface is provided on the top surface of a disk-shaped flat plate. The pair of electrode rods 10 is inserted upward from below the supporting portion 22, and the pair of electrode rods 10 are supported in a state where the pair of electrode rods 10 protrude from the upper part of the flat plate. By setting the angle of the inclined surface optimally, the pair of electrode rods 10 is arranged to face obliquely upward. The protruding lengths of the respective electrode rods 10 from the support portion 22 are the same, and the respective electrode rods 10 are fixed to the support portion 22 in a state of being arranged with a predetermined distance therebetween. A communication hole 22H is provided in the flat plate of the support portion 22 . Carbon dioxide, metal, and the like generated by the arc discharge are introduced to the side of the fan 23 or the adsorption unit 25 through the communicating hole 22H.

The thermoelectric cooler 24 is a device that converts heat into electricity using a Peltier element. The thermoelectric cooler 24 is arranged at the lower part of the electrode rod 10 to cool the heat generated by the arc discharge, and the electric fan 23 generated by the thermoelectric cooler 24 is used at the same time. The thermoelectric cooler 24 is disposed so that the heat-absorbing side of the thermoelectric cooler 24 faces the side (upper side) of the electrode rod 10 and the heat-radiating side of the thermoelectric cooler 24 is in close contact with the heat sink of the fan 23 . The fan 23 is driven by a motor incorporated in the fan 23 to generate wind, thereby cooling the periphery of the electrode rod 10 . In addition, "guiding the gas (including carbon dioxide or metal oxide, etc.) generated by the arc discharge to the adsorption part 25 is promoted, and at the same time, the gas passing through the adsorption part 25 is discharged to the outside from the exhaust hole 20H provided on the side surface of the irradiation part 20." " flow. In addition, instead of using a thermoelectric cooler, the fan 23 can be connected to a power source to drive it.

The adsorption unit 25 is disposed below the fan 23 . The adsorption portion 25 is a portion that adsorbs gases such as carbon dioxide or metal oxides generated by combustion (arc discharge). FIG. 4 is a diagram schematically showing the structure of the adsorption unit 25 . As shown in FIG. 4 , the adsorption unit 25 is composed of shell parts 25A, 25B and an adsorption material 25C. The adsorbent 25C is laid on the lower portion of the shell portion 25A and the inside of the shell portion 25B. The shell portion 25B has a combined structure of a cylindrical outer cylinder and a funnel-shaped (triangular push-shaped) inner cylinder. Adsorbent 25C is arranged between the inner cylinder and the outer cylinder. The radius of the funnel-shaped inner cylinder gradually decreases from above to below, and opens in a circular shape at the lower end of the shell portion 25B. That is, the shell part 25B has an opening part penetrated from the up-down direction inside. With the adsorbent 25C arranged on the shell portion 25A, the shell portion 25B is arranged on the inner side above the shell portion 25A. The gas or the like that intrudes from above the shell portion 25B passes through the adsorbent 25C laid on the shell portion 25B, while the gas sent downward passes through the adsorbent 25C laid on the shell portion 25A. At this time, carbon dioxide, metal oxides, and the like contained in the gas are adsorbed by the adsorbent 25C. Thereby, when the gas is exhausted to the outside through the exhaust hole 20H, harmful substances can be removed from the gas. By forming a plurality of hole portions 25H on the outer peripheral portion of the upper portion of the shell portion 25A, the gas passing through the adsorbent 25C is promoted to be exhausted from the exhaust holes 20H. In addition, the case part 25A and the case part 25B do not have to be used in combination, and only one of them may be used.

Regarding the conditions of the absorbent material, "it is easy to replace when the number of times of use is exceeded", "it can quickly absorb harmful substances", "it can be easily manufactured", "it can also withstand high temperatures", "it is odorless", "it is a safe material ", "will not easily release absorbed gas, etc.", are necessary conditions. In addition, it is necessary to consider: "Even ordinary households can throw away used adsorbent materials directly", and "Adsorbent materials do not contain lithium and other metals that are related to environmental pollution such as land and rivers." The material and manufacturing method of the adsorbent 25C developed based on the above point of view will be described. The material of adsorption material 25C is to crush charcoal (charcoal) and zeolite into pulverized powder at a volume ratio of 2-1:1, and mix ash and feldspar powder at a volume ratio of 0.5-1:2, and then mix a small amount of water and Alkaline electrolyzed water to make it moderately hydrated, and then mixed with silica gel at a volume ratio of about 1 to 2.5. Ash is divided into wood ash, etc., and contains potassium, magnesium or calcium. Feldspar is a white clay powder used in making pottery. Its ingredients include: 70-80% silicon oxide, 18-25% aluminum oxide, 5-12% potassium oxide, 3-10% sodium oxide, 0.1% iron oxide, Calcium 0.1-0.2%, magnesium oxide 0.01-0.05%, etc. Feldspar is mined in various parts of the world, such as India and Japan, and its composition and composition will change more or less depending on the place of production. Feldspar contains less calcium oxide than other ingredients, so if calcium oxide is further added, the absorption efficiency will increase. In addition, even if there is no feldspar, it is conceivable to mix several kinds of clay powders (mainly increasing the content of potassium oxide, sodium oxide, calcium oxide, magnesium oxide, etc.) used for pottery or fired products. The reaction with carbon dioxide, as shown below, is potassium oxide to potassium carbonate, sodium oxide to sodium carbonate, and calcium oxide to calcium carbonate. _K2O ＋ _H2O →2KOH 2KOH＋ _CO2 → _{K2CO3 ＋ H2O Na2O} ＋ _H2O → _2NaOH 2NaOH＋ _CO2 → _Na2CO3 ＋ _H2O CaO＋ _H2O →Ca(OH) ₂ Ca(OH) ₂ ＋ _CO2 →CaCO ₃ +H ₂ O Alkaline electrolyzed water is produced by electrolyzing water or salt water on the negative side. Table 2 shows an example of the composition of the adsorbent 25C in terms of mass.

Fig. 5 is a diagram schematically showing a light energy enhancement mechanism formed as a reflector. In FIG. 5 , a reflection plate 21M made of metal (stainless steel) is arranged inside the cover portion 21 as a light energy enhancement mechanism, and a groove portion 21G is formed on the surface of the reflection plate 21M. By disposing the reflecting plate 21M, the light generated by the arc discharge is reflected, so that the amount of light radiated toward the side of the user is increased to enhance energy. In addition, by forming the groove portion 21G on the surface of the reflection plate 21M, the intensity of the light can be enhanced by utilizing the refraction and reflection effect or the radiation effect of light. The groove portion 21G is formed by parallel grooves with a width of about 100 μm and formed vertically and horizontally. The widths of the plurality of trenches are not limited to the above, and need not be parallel. In addition, it does not necessarily have to be formed in a lattice shape, and only vertical grooves or horizontal grooves may be formed. The grooves may also be formed in a honeycomb shape or the like. By changing the number, length, depth, shape, arrangement or combination of grooves, the intensity of light energy can be adjusted, and the phototherapy device 1 can be used more effectively. In addition, forming the groove part 21G means forming a concave line or a convex part on the surface of the reflection plate 21M. Thinly coating the surface of the reflecting plate 21M with aluminum or silver can also achieve the effect of enhancing energy. In addition, the location where the reflection plate 21M or the groove portion 21G is formed is not limited to the cover portion 21 . The reflection plate 21M or the groove portion 21G may also be formed on the support portion 22 supporting the electrode rod 10 or other positions close to the light source.

Next, an electronic circuit built in the main body 30 of the phototherapy device 1 will be described. FIG. 6 is a block diagram showing a schematic structure of an electronic circuit. As shown in Figure 6, the basic structure of the electronic circuit of the present invention is composed of a converter, an inverter, a transformer, and a smooth rectification circuit, and a control circuit (control circuit) and a voltage circuit are assembled therein. For the converter part, it is advisable to use a diode & capacitor circuit or a 4-diode & capacitor rectifier circuit using a large-capacity capacitor and diodes to form a circuit as simple as possible. In the inverter part, the circuit using MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor, Metal-Oxide-Semiconductor Field-Effect Transistor) shown in Figure 7 and the circuit using IGBT (Insulated Gate Bipolar Transistor) shown in Figure 8 can be used. , insulated gate bipolar transistor) circuits. In the IGBT circuit, every two IGBTs form a pair, and the AC component is formed by high-speed switching on and off. After AC conversion by high-frequency transformer, smooth rectification is carried out by diode and choke coil, and stable arc light with suppressed pulsation can be obtained. By using a high-frequency rectification circuit using MOSFET or IGBT, the size and weight of the phototherapy device can be reduced. In order to stabilize the light generated by arc discharge, it is necessary to suppress voltage fluctuations and improve current rectification. This can be achieved by using MOSFETs or IGBTs that can be turned on and off at high speed.

Fig. 9 is a perspective view showing another embodiment of the phototherapy device. The phototherapy device 100 shown in FIG. 9 is a stationary device. As shown in FIG. 9 , the phototherapy device 100 is composed of a pair of electrode rods 110 , an irradiation unit 120 movable in the vertical direction, and a main body unit 130 with built-in electronic circuits and the like. The electrode rod 110 and the main body portion 130 have the same structure as the electrode rod 10 and the main body portion 30 respectively, so the description thereof will be omitted. The irradiation part 120 is composed of the following components: a cover part 121, which covers a part around the electrode rod 110; a support part 122, which supports the electrode rod 110; a pillar 123, which supports the support part 122, and makes the support part 122 can move up and down; the sensor 124 is used to detect the position of the user; and the camera 125 is used to photograph the user. The support part 122 (including the cover part 121 etc.) is arrange|positioned so that it can move in an up-down direction with respect to the support|pillar 123. As shown in FIG. For example, a rack and pinion method is used in which a rack is provided on the pillar 123 and a gear is provided on the supporting part 122 so that they can move relative to each other in the up and down direction. A motor is built in the supporting part 122, and the gears can be powered to rotate.

The sensor 124 is, for example, an ultrasonic sensing sensor. The sensor 124 is mounted on the cover part 121 of the irradiation part 120 . The sensor 124 detects whether there is a human body within a certain distance away from the phototherapy device 100 . When the sensor 124 determines that there is a human body for a certain period of time, it drives the motor built in the supporting part 122 to move the supporting part 122 up and down relative to the pillar 123 . At this time, the supporting part 122 moves while detecting the distance between the sensor 124 and the human body. For example, the determination of "recognize the part where the width of the human body suddenly narrows as the neck of the human body, etc." is performed. In this way, even if the height of the user changes, the supporting portion 122 of the electrode rod 110 can still be automatically moved to an optimal position.

An infrared sensor can also be combined with the sensor 124 . By sensing the temperature of the human body, it is possible to prevent erroneous actions caused by objects other than people. In addition, a thermal imager can also be used to read the thermal imaging image of the heat source as it is, and move the support portion 122 of the electrode rod 110 to the lower part of the head circle. The camera 125 can also be used to take pictures of the head of the human body and analyze it with image recognition software, so as to move the supporting portion 122 of the electrode rod 110 to an optimal position. In addition, although not shown in the figure, similar to the phototherapy device 1 , the irradiation unit 120 of the phototherapy device 100 also has an adsorption unit or a fan built inside.

Fig. 10 is a perspective view showing another embodiment of the phototherapy device. As shown in FIG. 10, the phototherapy device 200 is composed of a pair of electrode rods 210, an irradiation unit 220 movable in the vertical direction, and a main body unit 230 with built-in electronic circuits and the like. The irradiation part 220 is composed of the following components: a cover part 221, which covers a part of the electrode rod 210; a support part 222, which supports the electrode rod 210; a pillar 223, which supports the support part 222, so that the support The part 222 is movable in the vertical direction; and the holding part 224 is annular and holds a plurality of pillars. The electrode rod 210 , the body portion 230 , the cover portion 221 , and the support portion 222 have the same structure as the electrode rod 110 , the body portion 130 , the cover portion 121 , and the support portion 122 , so descriptions thereof are omitted. The phototherapy device 200 has a plurality of irradiation units 220, and has a structure that can be used by a plurality of people at the same time. By arranging the pillars 223 at a plurality of positions of the holding part 224, a plurality of irradiation parts 220 can be arranged with a predetermined distance therebetween. In addition, although not shown in the figure, the phototherapy device 200 can also have sensors or cameras like the phototherapy device 100 . By using a sensor or a camera, the position of the illuminating unit 220 can be adjusted according to the heights of a plurality of users. In addition, although not shown in the figure, similar to the phototherapy device 1 , the irradiation part 220 of the phototherapy device 200 also has an adsorption part or a fan built inside.

Fig. 11 is a perspective view showing another embodiment of the phototherapy device. As shown in FIG. 11 , the phototherapy device 300 is composed of a pair of electrode rods 310 , an irradiation unit 320 capable of moving up and down, and a main body unit 330 with built-in electronic circuits and the like. The irradiation part 320 is composed of the following components: a cover part 321, which covers a part of the periphery of the electrode rod 310; a support part 322, which supports the electrode rod 310; The part 322 is movable in the up and down direction. The electrode rod 310 and the main body portion 330 have the same structure as the electrode rod 110 and the main body portion 130 respectively, so the description thereof will be omitted. In the phototherapy device 300, the opening of the cover part 321 of the irradiation part 320 has a substantially rectangular shape, and the area of the opening part is formed to be large. Thereby, a structure "can irradiate a user's whole body in a wide area at once, and multiple people can share one irradiating part 320" is formed. In FIG. 11 , an example in which the number of support portions 322 (cover portions 321 ) is two is disclosed, but three or more support portions 322 (cover portions 321 ) may be arranged. In addition, although not shown in the figure, the phototherapy device 300 can also have sensors or cameras like the phototherapy device 100 . By using a sensor or a camera, the position of the irradiation unit 320 can be adjusted according to the user's height and the like. In addition, although not shown in the figure, like the phototherapy device 1 , the phototherapy device 300 also has an adsorption part or a fan built in it.

Fig. 12 is a plan view showing another embodiment of the supporting portion. As shown in FIG. 12 , the supporting portion 422 is constituted by a pair of supporting portions 422A, 422B independently supporting a pair of electrode rods 410 , 410 . While the position of the support portion 422A is fixed, the support portion 422B has a movable structure in a direction of approaching and a direction of separation from the support portion 422A. Thereby, the distance (light source distance) between a pair of electrode rod 410 can be adjusted to the optimum structure. The supporting parts 422A and 422B are arranged at an angle so as to approach each other toward the front end side of the electrode rod 410 . A thread groove is formed on the shaft portion 423 to which the support portion 422B is coupled. The shaft portion 423 is inserted into a screw hole formed in the fixing portion 424 . By rotating the adjusting knob 425 fixed on the front end of the shaft part 423 , the shaft part 423 is rotated relative to the fixing part 424 . Thereby, the supporting part 422B is relatively moved with respect to the supporting part 422A. By changing the distance of the light source, the intensity of light can be adjusted, or the distance between a pair of electrode rods 420 can be made closer when the electrode rods 410 are further consumed. The automatic adjustment mechanism of the energized movement supporting part 422B may also be constituted by assembling a motor or the like. If the structure is such that both the left and right support parts are moved, a high voltage may be applied to both the left and right support parts while the left and right support parts are connected, and a short circuit may occur between the support parts. By constituting a structure in which only one support part moves, it is possible to prevent a short circuit between the support parts.

Next, the relationship between the composition of the electrode rod and the wavelength of the light irradiated by the phototherapy device will be described. Fig. 13 shows the spectrum of light irradiated by the phototherapy device when a conventional electrode rod mainly composed of potassium and iron is used. This is the result of measuring the wavelength of the light emitted by the arc discharge within the band of 230nm to 850nm using an optical wavelength measuring device (OHSP350C and 350UV) manufactured by HOPOOCOLOR. The horizontal axis represents the wavelength (nm), and the vertical axis represents the emission intensity of each wavelength. As shown in FIG. 13 , when the conventional electrode rod is used, the luminescence peak appears around 385 nm due to potassium, and the luminescence peak appears around 650 nm due to iron. All in the visible light band (380nm ~ 780nm). In addition, in the ultraviolet band (less than 380nm), it shows low luminous intensity.

Fig. 14 shows the spectrum of light irradiated by the phototherapy device when titanium nitride (TiN) is added to the conventional electrode rod. By adding titanium nitride, the light intensity of ultraviolet rays can be suppressed while shielding the ultraviolet band. In addition, it is possible to irradiate light having a pattern that "increases the number of emission peaks or expands the width of the wavelength band having peaks". This is because, among titanium compounds, titanium nitride is very hard and has the property of absorbing light in the visible light and ultraviolet bands, so light absorption and scattering effects occur. Therefore, as shown in FIG. 14 , a luminescence peak is newly added to both the short-wavelength side and the long-wavelength side of the luminescence spectrum peculiar to potassium near 385 nm. Especially in the visible light band below 500nm, the number of luminescence peaks increases, and the wavelength band of the peaks also expands. It is also known that the scattering effect will spread over the whole wavelength band with the increase of the addition amount of TiN. It can be seen that when a small amount of titanium nitride is added, if the core part of the electrode rod is an aggregate of several metal elements and arc discharge is performed, the free electrons on the surface of the metal particles will collectively vibrate due to the interaction with light, Fluorescence resonance energy transfer and light emission from several energy levels will occur between it and other mixed elements due to surface plasmon resonance and light diffraction, so the light emission will be enhanced on the long wavelength side, and the light emission peak will increase. .

FIG. 15 shows the spectrum of light irradiated by the phototherapy device when titanium nitride (TiN) and calcium (Ca) are added to the conventional electrode rod. It can be seen that the light intensity in the near-infrared band (near 600nm) is increased by adding calcium. As the amount of titanium nitride added increases, the overall light intensity will decrease due to the amount of light absorbed. By adding a small amount of calcium compound, the overall luminosity can be enhanced. The luminous intensity is enhanced corresponding to the addition amount of the calcium compound having a luminescent spectrum in the visible light band, and can be enhanced to about 5 times.

FIG. 16 shows the spectrum of light irradiated by the phototherapy device when titanium nitride (TiN) and silver (Ag) are added to the conventional electrode rod. By adding silver, a wide range of luminous intensity enhancement from visible light above 500nm to infrared band is found. In addition, it can be seen that the addition of titanium nitride has the effect of significantly reducing the not-uncommon ultraviolet bands [UVA (ultraviolet A, ultraviolet A) and UVB (ultraviolet B, ultraviolet B)]. Table 3 shows that when the electrode rod contains potassium, by adding silver and calcium, UVB and UVC (ultraviolet C, ultraviolet C), which are harmful to organisms, will be reduced to a level extremely close to zero. [table 3] Electrode rod material UV intensity (uW/cm ² ) UVA UVB UVC total Titanium Nitride + Potassium 58.9 5.6 3.0 67.5 Titanium Nitride + Potassium + Silver + Calcium 19.4 0.4 0 19.8

Next, the experimental results for confirming the efficacy of the adsorption material of the present invention are revealed. The gas generated when the electrode rod is burned for 1 minute and 30 seconds due to arc discharge is sucked into a 160cc syringe, and connected to another syringe containing 30cc of absorbent material, and then sucked and extruded by the pump 10 times. Table 4 shows the results of measuring the amount of carbon dioxide contained in each of the five types of absorbent materials using carbon dioxide detector tubes. [Table 4] No. Adsorbent material carbon dioxide before adsorption Carbon dioxide after adsorption 1 Charcoal + zeolite (crushed) + silica gel + water 3000ppm 1800ppm 2 1+ lignin 3000ppm 2500ppm 3 1+ash 3000ppm 1500ppm 4 1+ash+feldspar 3000ppm 500～600ppm 5 4+ alkaline electrolyzed water (replace water) 3000ppm 300ppm (minimum)

As shown in Table 4, the carbon dioxide concentration in the gas collected for combustion was 3000 ppm. Although charcoal, zeolite, silica gel, and water are improved to 1800ppm, the absorbent material with ash content is improved to 1500ppm, and the absorbent material with feldspar is further improved to 500-600ppm. Then, it can be improved to 300ppm (that is, 1/10) by further adding the absorbent material of alkaline electrolyzed water. If this safe and effective carbon dioxide absorbing material is used, it can be used to greatly reduce the burden on the environment caused by the burning of electrode rods, and it is not limited to the technical field of phototherapy devices, and can also be used for the purpose of reducing carbon dioxide or as a carbon dioxide absorbing material. As for the adsorption material, the absorption rate is the best if the charcoal and zeolite are pulverized into powder, mixed with ash and feldspar powder, and then a small amount of water and alkaline electrolyzed water are added to the silica gel and stirred to form viscosity and water retention. . The types of feldspar include potash feldspar, soda feldspar, Indian feldspar, pottery stone and the like. Examples of the composition of feldspar include SiO ₂ : 60-66%, Al ₂ O ₃ : 18-24%, CaO: 0.1-0.3%, MgO: 0.01-0.04%, K ₂ O: 5-12%, %, Na ₂ O: 3-5%. Electrolyzed water refers to what is produced on the negative electrode side when water is electrolyzed.

Next, the experimental results for confirming the efficacy of the light energy enhancement mechanism of the present invention are revealed. Table 5 reveals the experimental results of comparing the light intensity caused by the light energy enhancement mechanism. A flat plate made of stainless steel (SUS304) is arranged on a flat plate of 100mm×100mm×1mm, a vertical groove is formed on a stainless steel flat plate, and vertical and horizontal grooves are formed on a stainless steel flat plate, respectively, and no stainless steel plate is arranged for comparison. A total of 55 grooves with a width of 0.1 mm and a depth of 0.5 mm were formed on the metal plate of the vertical groove within a range of 100 mm in length and 35 mm in width near the center. For the metal plate of the vertical and horizontal grooves, a total of 55 vertical grooves with a width of 0.1mm and a depth of 0.5mm are formed in a range of 100mm in length and 35mm in width near the center, and the same A total of 20 transverse grooves were formed orthogonally to the groove width and depth. A flat plate is arranged near the irradiation part, and the light intensity of the reflected light when the light is irradiated is measured. The unit of value is expressed in lux (lx). [table 5] No. no stainless steel Stainless steel Stainless steel + longitudinal groove Stainless steel + vertical and horizontal grooves 1 1723 1988 --- --- 2 2563 --- 4125 --- 3 2399 --- 4473 --- 4 1682 --- 4014 --- 5 2399 --- 6036 --- 6 3318 --- --- 10690 7 2684 --- --- 21190 8 1684 --- --- 16060

As shown in Table 5, it was confirmed that the light intensity was enhanced by arranging the flat plate made of stainless steel. In addition, it was confirmed that by forming vertical grooves or vertical and horizontal grooves in a flat plate made of stainless steel, the light intensity is further enhanced. Compared with the configuration without stainless steel plates, the light intensity of the configuration with vertical and horizontal grooves is increased by about 3 to 10 times.

Next, using the phototherapy device of the present invention, a therapeutic effect experiment was carried out on patients with infectious diseases. The evaluation is based on groups with acute respiratory symptoms (runny nose, cough, sputum, sneezing, sore throat, etc.), and further grouped by whether they have a fever. In addition, pay attention to the white blood cell part by blood test. When it is a bacterial infection, white blood cells or CRP [C-Reactive Protein, C-reactive protein (inflammation response index)] will increase according to the severity of the disease, but generally speaking, there are many cases where it does not increase when it is a viral infection, so A leftward shift of the nucleus in the leukocyte fraction will be noted. We focus on the fact that an increase in the number of lymphocytes (decrease in the number of neutrophils) is observed in the white blood cell fraction when it is a viral infection, and an increase in the number of neutrophils (a decrease in the number of lymphocytes) is observed in the case of a bacterial infection. number will drop). In addition, when bacteria and viruses were identified from the culture results of the sputum test, the process was also evaluated. Table 6 reveals the normal ranges for the number of neutrophils and lymphocytes. [Table 6] male female Normal range for neutrophil count 45.2～68.8% 49.7～72.7% Normal range of lymphocyte count 26.8～43.8% 24.5～38.9%

Regarding experiment 1, among a total of 40 patients in the age group of 30 to 80 who showed symptoms of acute respiratory infection (runny nose, cough, phlegm, sneezing, sore throat, chills, etc.), Take 20 patients with a fever of 37.5 degrees or more and 20 patients without fever as subjects, and irradiate the head to the front chest and the right upper abdomen of the liver with light with the phototherapy device of the present invention, 2 to 3 times a day, each time 3 to 10 minutes. For the 20 people who did not have a fever, the white blood cells were still within the normal range after blood drawing, which should be the earliest infection period of bacterial or viral infection. After 2 days of irradiation with light therapy equipment, it was confirmed that all symptoms of 20 people disappeared. Among the 20 patients with a fever of 37.5 degrees or higher, 10 were confirmed to have increased neutrophils in the white blood cells, which should be in the early stage of bacterial infection, and CRP was also observed to increase to 0.4-7. The 6 people whose lymphocytes were confirmed to be elevated should be in the early stage of viral infection. The 4 people whose white blood cell part is within the normal range should be the earliest stage of infection. Use the phototherapy device of the present invention for these patients for 2 to 5 days. On the 2nd and 3rd day, 14 out of 20 people had their fevers and returned to normal body temperature. On the 4th to 5th day, the remaining 6 people had their fevers and returned to normal body temperature. Respiratory symptoms (runny nose, cough, phlegm, sneezing, sore throat, chills, etc.), 8 out of 20 people disappeared on the 2nd day, 6 people disappeared on the 3rd day, and remained on the 4th to 5th day. The next 6 people disappeared. In addition, it was confirmed that the blood drawing data after 1 week to 10 days tended to normalize. It teaches that the group with increased neutrophil count is bacterial infection, and the group with increased lymphocyte count is viral infection. For patients with the earliest respiratory symptoms or mild patients without fever, the improvement effect is significant, the first There are many cases where the symptoms disappeared on the first day, and it was confirmed that the symptoms of all members improved on the second day. In addition, it is known that even if you have a fever, the improvement effect will gradually increase by using the phototherapy device for several days. If it is early, a certain degree of efficacy will be confirmed quickly.

Regarding experiment 2, 2 people (1+ to 2+) who had a positive result of MRSA (Methicillin-Resistant Stapbylococcus Aureus) in the throat bacterial culture test for 6 months and a positive result of MRSA One person who has been positive for 3 months (1+) totals a total of 3 patients. From the head to the front chest and the back of the right upper abdomen, the phototherapy device of the present invention is used to irradiate light twice a day (morning and evening) , irradiated for 5-10 minutes, a total of 5 days. The throat swab specimens taken on the 7th day from the start of irradiation were confirmed, and all three were negative for MRSA (-).

Regarding experiment 3, among the 4 patients whose saliva test was PCR positive for SARS-CoV-2, 2 patients with a fever of 37.5 degrees or more and 2 patients without a fever were tested from the head to the front chest and right upper abdomen , use the phototherapy device of the present invention to irradiate with light, 2 to 3 times a day, 5 to 10 minutes each time, and continue to irradiate for 5 days. On the 5th day after the irradiation, the PCR examination of the nose and throat swab samples was carried out, and all 4 people were judged to be negative.

The examination data in Experiments 1 to 3 are analysis results of examination centers affiliated with medical institutions. From Experiment 1, it is known that the group with increased neutrophil count is bacterial infection, and the group with fever but no leukocyte nuclear shift or increased lymphocyte count is viral infection. For patients with early or mild symptoms without fever, the improvement effect is remarkable, and there are many cases where the symptoms disappear after a few hours. If it is in the early stage, the effect can be quickly and surely exerted to a certain extent. It is also found that there are many cases where improvement in symptoms has been confirmed for patients with fever as well, and the improvement occurs at an early stage. From experiments 2 and 3, it can be seen that it is also effective against MRSA and SARS-CoV-2.

As described above, by adding titanium nitride to the electrode rod, the conventional luminescence peak pattern can be changed. It can make the luminescence peak also appear on the short-wavelength side of the original luminescence spectrum of potassium, which has a luminescence peak in the visible light range, and shield the UVA range. It can also use the light absorption and scattering effect or plasmon effect caused by titanium nitride to form an increase. patterns of several luminescence peaks. The property of widely interfering with the emission peaks of other elements and affecting them has not been observed in other elements or metal compounds. By adding titanium nitride, there is no need to add other harmful metal elements that have emission spectrum in the ultraviolet range, and it is possible to irradiate light having a pattern with an expanded wavelength band width while shielding the ultraviolet range. Furthermore, it can be seen that by adding silver or calcium, the luminous intensity in the near-infrared range will be enhanced, and the therapeutic effect on the living body will also be increased. We believe that these organisms tend to absorb light in the near-infrared range around 600nm to 900nm, and we use this point to exert effects on organisms. We believe that the effect on viruses or bacteria is due to "the original emission spectrum wavelength of potassium is expanded from the short wavelength side", "the number of emission peaks is also increased", "use of near-infrared range", "infrared effect, etc. are effective Luminous Enhancement" caused by. In this way, it can be effective against viral and bacterial infections. In addition, harmful ultraviolet wavelengths such as UVB and UVC can be reduced by adding silver or calcium.

The efficacy of ultraviolet rays to kill viruses and bacteria is well known. However, for the human body, just bathing in strong ultraviolet rays will cause too much damage to the skin or cells, so it cannot be used directly. We found that the present invention coordinates and utilizes light energy in the near-infrared range that is easily absorbed by the body, thereby reducing the necessary light form in the ultraviolet band to exert effects on the human body. Then, the infrared heating effect caused by the burning of carbon promotes the body's response to function effectively. In addition, in order to exert an effect on the pathogens ingested by the body, the strong light energy caused by the arc discharge is necessary. In order to obtain light in the ultraviolet range, if it is used for an element with a luminous peak in the ultraviolet range, the intensity of the ultraviolet light will be too high, and the adverse effects on the human body will also become greater, and the burning products of the arc discharge will further cause adverse effects on the human body. Taking this into consideration, by utilizing elements that have conventionally not had a luminescence peak in the ultraviolet region and have a luminescence peak in the visible region, and extending the luminescence peak to the ultraviolet region, the necessary amount of ultraviolet light can be minimized. obtain the necessary effect.

The phototherapy device of the present invention not only has the warming effect or visceral activation effect caused by the infrared effect, but also prevents viral or bacterial infections, etc., through the effect of effectively intensified light energy with a wide range of effective wavelengths. Even after bacteria or viruses are inhaled into the body, by using a phototherapy device to prevent the proliferation in the body until the symptoms are found, the onset can be prevented if it is early. When the pathogens proliferate in large quantities in the body, the effect of "reducing the number of pathogens and improving the condition after the onset" can be obtained. For the purpose of prevention or before the onset of the disease, when you go home after going out, use it on the neck to the front chest, about 1 to 2 times a day, about tens of seconds to a few minutes each time, and you can get the effect. If it is after the onset, it is advisable to use it to irradiate the whole body as much as possible centered on the right upper abdomen of the former chest or liver, about 2 to 4 times a day, for a few minutes to 15 minutes each time.

Carbon (black carbon, etc.) that accounts for more than half of the composition of the electrode produces carbon dioxide when burned. It is inappropriate from the viewpoint of environmental pollution to discharge this carbon dioxide as it is. In addition, the metal oxides produced by combustion will produce odor, and inhalation by users may also cause adverse effects on the human body. Alleviation of these problems has been achieved through the use of absorbent materials including clay powder, wood ash, charcoal and zeolites. The carbon dioxide or metal oxides produced by the combustion are absorbed by the absorbent material to prevent the user from inhaling the produced substances directly. Furthermore, by using a thermoelectric cooler to drive a fan, the adsorption of carbon dioxide or metal oxides by the absorbing material can be facilitated.

For the electronic circuit of the phototherapy device, MOSFET or IGBT are used. Conventional phototherapy devices use large and heavy transformers. By using MOSFETs or IGBTs, they can be made smaller and lighter. In this way, the phototherapy device can be hand-held and carried. In addition, conventional large-scale transformers are easily affected by the use environment due to coil heat generation, temperature, and humidity, and are not suitable as public-use devices that can be used frequently for a long time. Furthermore, depending on the usage environment, there may be safety issues such as overvoltage concerns. In addition, the secondary side power loss of the transformer caused by iron loss and copper loss is also a disadvantage. The present invention can also solve these problems by using MOSFET or IGBT.

A metal reflection plate is arranged near the light source, and grooves are formed on the reflection plate, thereby enhancing the intensity of the light. By adopting these structures, it is possible to generate light with a minimum of electric power. In addition, the phototherapy device can be used even when the subject is far away from the irradiated part. For example, it is also effective when irradiating light to livestock or animals located far away, or when irradiating light to large animals with thick skin. In addition, it may also be effective when there are viruses, etc. that require strong light energy to eliminate them.

The phototherapy device of the present invention is not limited to personal use or use in hospitals and other places. It can also be used for public use by setting up phototherapy devices in airports, stations and other transportation facilities, buildings, commercial facilities, concert halls, sports viewing venues and other places where many people gather. For example, by exposing all passengers to light at the boarding gate of an aircraft, it is possible to prevent the spread of infectious diseases in the aircraft or the entry of pathogens from abroad. That is, we believe that it is effective in preventing the spread of infectious diseases caused by the movement of people and suppressing infectious diseases that have spread regionally or widely. In addition, unlike drugs or vaccines, it does not depend on the type of bacteria or virus, and the same efficacy can be expected for mutant types, and drug-resistant bacteria are not likely to appear. Furthermore, not only the human body but also its efficacy against livestock and animal infectious diseases can be expected.

The invention is not limited to an embodiment as a phototherapy device. It may also be an embodiment of an electrode rod including titanium nitride used as a pair of electrodes of a phototherapy device.

The mixing ratio of the materials of the core material portion of the electrode rod shown in this embodiment is an example at best, and the configuration of the present invention is not limited to this ratio. In addition, the adsorption material of an electrode rod is only an example at most, and the structure of this invention is not limited to this ratio. Adjust the mixing ratio of the absorbent material based on the viscosity and water retention. In addition, in the present invention, substance terms such as iron and calcium are concepts including iron compounds and calcium compounds.
